Battery charger IC

18 August 2010 Power Electronics / Power Management

Advanced Analogic Technologies introduced the AAT3698, a single-input 1,6 A linear charger with 28 V input protection and 50 mA low dropout (LDO) to manage the charging, sequencing and protection of Lithium (Li)-Ion and Lithium Polymer batteries.

The device is a small standalone charger solution that requires only two resistors and four small capacitors to operate and comes in a small, lead-free, 14-pin 4 x 4 mm thin quad flat no-lead (TQFN) package. It precisely regulates battery voltage for Li-Ion/Polymer battery cells through a low RDS(ON) switch after it has reached 4,2 V. The charging current can be set by an external resistor up to 1,6 A.

Besides the IC’s built-in OVP circuit that helps prevent damage to the battery and the charging circuitry, other fault conditions are monitored in real-time. In case of an over-current, battery over-voltage, short circuit or over-temperature failure, the device will automatically shut down, thereby protecting the charging device, control system and the battery under charge. A status monitoring output pin is provided to indicate charging activity.
